This is the most complex item. It contains very important information from the point of view of ATS therefore a careful and correct filling of this field is required. Mistakes in this field may be an indirect reason for such hazardous occurences as airspace infringement.
In item 15 insert:
a) the first cruising speed as described in (A) below,
b) the first cruising level as described in (B) below, and
c) the route description as described in (C) below.
(A) Cruising Speed (maximum 5 characters)
Insert the true airspeed for the first or the whole cruising portion of the flight, in terms of:
a) kilometres per hour expressed as “K” followed by 4 figures
Example: K0220 (which means 220 km/h true airspeed)
b) knots expressed as “N” followed by 4 figures
Example: N0175 (which means 175 knots true airspeed)
There is also an option to indicate speed as Mach number but as it is not used by GA no details will be provided.
General aviation example: N0150 (assuming that You will fly with speed 150 knots)
(B) Cruising Level (maximum 5 characters)
Insert the planned cruising level for the first or the whole portion of the route to be flown, in terms of:
a) flight level, expressed as “F” followed by 3 figures or
Example: F085 (which means flight level 085),
b) standard metric level in tens of metres, expressed as “S” followed by 4 figures
Example: S0150 (which means 1500 metres)
c) altitude in hundreds of feet, expressed as “A” followed by 3 figures
Example: A055 (which means 5500 feet altitude)
d) altitude in tens of metres expressed as “M” followed by 4 figures
Example: M0610 (which means 6100 metres altitude)
e) only for uncontrolled VFR flights, the letters “VFR”.
General aviation example: A065 (assuming that You will fly at 6500 feet altitude)
(C) Route (including changes of speed, level and/or flight rules)
To fill in the “Route” field use points (1) to (6) below and after each element add a single space.
(1) Flights along designated ATS Routes:
Insert, if the departure aerodrome is located on, or connected to the ATS route, the designator of the first ATS route.
If the departure aerodrome is not on, or is not connected to the ATS route, insert the letters DCT, followed by the joining point of the first ATS route and followed by the designator of the ATS route.
Example: DCT RONEX L617 …
Then insert each point at which either a change of speed or level, a change of ATS route, and/or a change of flight rules is planned.
Example: TRZ/N0200A080 IFR (which means that at point TRZ you are to change speed to 200 knots, altitude to 8000 feet and request to change flight rules to IFR).
After each point add the designator of the next ATS route segment, even if the same as the previous one or by DCT , if the flight to the next point is outside a designated route, unless both points are defined by geographical co-ordinates.
(2) Flights outside designated ATS Routes:
Insert points normally not more than 30 minutes flying time or 370 km (200 NM) apart including each point at which a change of speed or level, a change of track, or a change of flight rules is planned or when required by the appropriate ATS authority(ies).
Insert DCT between successive points unless both points are defined by geographical co-ordinates or by bearing and distance.
(3) ATS route (2 to 7 characters)
Insert the coded designator assigned to the route or route segment including, where appropriate, the coded designator assigned to the standard departure or arrival route.
Example:R11
M857
UB10
SOXER2K
(4) Significant point (2 to 11 characters)
Insert significant points on Your route using their designators (2 to 5 characters) assigned.
Example:LN
KTC
TOSPO
If no coded designator has been assigned use one of the following ways:
(a) Degrees only (7 characters):
Insert 2 figures describing latitude in degrees, followed by “N” (North) or “S” (South) then followed by 3 figures describing longitude in degrees, followed by “E” (East) or “W” (West). Make up the correct number of figures, where necessary, by insertion of zeros.
Example:51N025E
(b) Degrees and minutes (11 characters):
Insert 4 figures describing latitude in degrees, and tens and units of minutes followed by “N” (North) or “S” (South), followed by 5 figures describing longitude in degrees and tens and units of minutes, followed by “E” (East) or “W” (West). Make up the correct number of figures, where necessary, by insertion of zeros.
Example:5220N03305E
(c) Bearing and distance from a navaid or navigation point:
Insert the identification of the navaid (normally a VOR) or the name of navigation point, in the form of 2 or 3 characters (navaid) up to 11 characters when name of the point is used, next the bearing from the navaid/point in the form of 3 figures giving degrees magnetic, next the distance from the navaid/point in the form of 3 figures expressing nautical miles. Make up the correct number of figures, where necessary, by insertion of zeroes.
Example 1: a point 170° magnetic at a distance of 20 NM from VOR “LDZ” should be expressed as LDZ170020.
Example 2': a point 130° magnetic at a distance of 12 NM from CONTI point should be expressed as CONTI130012.
(5) Change of speed and level (maximum 21 characters)
Insert the point at which a change of speed (more than 5% TAS) or a change of level is planned, expressed exactly as in (1), followed by an oblique stroke and both the cruising speed and the cruising level without a space between them, even when only one of these quantities will be changed.
Examples:LN/N0284A045
RUDKA/N0305F100
52N021W/K0260M080
4602N07805W/K0200F165
(6) Change of flight rules (maximum 3 characters)
Insert the point at which the change of flight rules is planned followed by a space and one of the following: VFR if from IFR to VFR or IFR if from VFR to IFR.
Examples:SUW VFR
XIMBA/N0284A090 IFR
